Bug: Unown sprite glitched in Pokédex in Gen2

[BeyondTheHorizon]

Hi, I discovered that when you check Unown as seen or caught in the Pokédex in PKHeX for a Gen2 save file, its sprite is glitched up in the game's Pokédex. I am not yet sure if this also happens for later Pokémon games. Here's a screenshot:

Are you sure it's not just the game?

Hi, I have since discovered that if the player finds an Unown naturally (walking around in the Ruins of Alph), Unown's sprite in the Pokédex appears correctly. It glitches up if the player adds Unown to their seen or caught Pokédex directly from PKHeX.

Would it be a good idea to allow the PKHeX user to select which Unown form to appear in the Pokédex when editing directly from PKHeX?

I personally don't think it's PKHeX's problem but I'm usually wrong about these things.

This is definitely a bug. There's a form flag for Unown which PKHeX doesn't set. It's at 0x1C82/0x2A82 for EU/US Crystal.

I should also add that I tried adding an Unown to my PC box while it wasn't checked in the Pokédex—in case any reader doesn't know, Pokémon are automatically checked as seen and caught in the Pokédex when created, if they weren't before—but its sprite in the Pokédex was glitched.

@BlackShark, do you know which hexadceminal values the Unown flag is set for Gold and Silver? It would help @Kaphotics fix this bug for all Gen II games.

now sets the first form encountered if none were prior:

Thanks for fixing the bug. Wish you well.
